The Schleifenbauer Intelligent Power Distribution Unit (PDU) is designed to distribute power for many years and without

problems. It is equipped with a Schleifenbauer data bus which makes it possible to read and manage many PDUs with a

single IP address. An ethernet port was added to the individual PDU’s so that alongside the advantages of a data bus, a

whole range of new options has become available.

Schleifenbauer PDUs bring together or merges the interests between IT and infrastructures, making it a real bridge builder.

The PDU may contain:

metered outlets

switched outlets

metered and switched outlets

passive outlets

Monitoring capabilities will be described in detail within this manual in coming sections.

This manual contains important safety instructions that should be followed during installation and operation of the PDU.

Please read this manual carefully since there may be serious or fatal personal injury and damage to the equipment if the

safety instructions, warnings and directions are not followed. Please save this document for future use.

E

Installation, maintenance and inspection of the Schleifenbauer Intelligent PDU must be carried out by adequately trained

persons according to NEN EN 50110-1, with full observance of the specifications of NEN EN 50110-1 and NEN 3140.

T

Before installing and putting the system into operation, check whether the characteristics of the electrical system to which

connection is to be made correspond to the product specifications.

The Schleifenbauer Intelligent PDU has been designed for connection to electrical systems that comply with IEC

60364 or in the Netherlands, NEN 1010.

The voltage, maximum permitted current and the number of phases must be correct. This information is displayed

on the front side of the PDU.

The maximum permitted power must be taken into account with regard to the maximum length and the diameter

of the connecting lead.

The values and characteristics of the in-series protective devices must match the PDU and the protective elements

included in it.

The environmental factors must correspond to the product specifications.

V

Aer opening the cardboard box and removing the packaging material, the PDU should be checked visually. The PDU

should not be put into operation if damage is detected such that safe and proper operation cannot be guaranteed. In such

cases, please contact Schleifenbauer Products BV.

Note that, in the case of PDUs that are equipped with an over voltage protection, the overvoltage protection and the

respective overcurrent protection (if applicable) must be inspected on a regular basis.


T

Each Schleifenbauer PDU is individually tested according to the NEN 3140 standard. Test reports are available on request.

For measurement of insulation resistance, the measuring voltage used must be lower than or equal to the

voltage according to the product specification.

C

The PDU may only be cleaned by wiping off the outside with a clean dry cloth.

The Schleifenbauer Intelligent PDUs are shipped in a GreenCart (rolling trolley) or are packaged in a cardboard box. Where

applicable, dispose the packaging material in a responsible manner, in accordance with local regulations. All of the

materials used for packaging can be recycled. Please contact Schleifenbauer Products BV to arrange return of your empty

GreenCart. Immediately aer receipt, check whether you have received all of the goods.

The following items are delivered for each PDU:

fixing materials: these can be attached to the PDU (19’’ or table-mounting brackets), or are delivered separately if

they have been ordered separately;

the installation manual (1 per shipment);

Please note that the PDU User Manual can be found online at http://schleifenbauer.eu

A

The following tools are needed to install the PDUs:

cage-nuts with bolts and washers

suitable screwdriver.

M PDU

How to mount a PDU horizontally (19 inch)? Each 19’’ rack bracket of a PDU has 4 holes for horizontal mounting in 19” racks. The holes are

positioned so that an appropriate fixing hole is always available for a PDU with a profile height of

1.5 U. Using one or two of the 4 holes allows mounting without wasting space.


http://schleifenbauer.eu/

How to mount a PDU vertically (= 0U)? I n the case of a PDU for vertical mounting, the connection lead is fed through a hole in the upper, bottom or front face.

There are 4 options for horizontal mounting:

How to install on a flat surface?...table top mount Gives the profile possibility to be mounted to a flat surface (tabletop). This

arrangement is used for:

vertical mounting to the bracing beams in the 19” cabinet

fixing to a mounting plate

mounting between the 19” uprights: the profile attaches to the front

of the uprights

The holes on the brackets are located as far as possible to the outside so

that it can also fit and tighten the bolts if a swivel gland has been placed

on the short side.

How to prevent hot spots in a cabinet? …sunken installation When power leads might block the flow of hot exhaust air, especially in

case of a 600mm wide cabinet, it is necessary to create flow space. This

can be done by using the “sunken installation brackets”. Because of the

shape of the bracket, it is possible to ‘partially sink’ the profile into the

cabinet and save space.

These mounting plates can be used for many different cabinets.

How to mount a PDU without tools? Toolless mounting is created by making attachment points on the rear of

the PDU housing. There is a wide range of cabinet brackets available, all in

which you can hang the PDU without using tools.

Toolless Mounting can be done as single PDU or double PDUs (see photo).

Mounting brackets can be custom made by Schleifenbauer.

How to achieve maximum mounting flexibility? ...mounting with profile clamps The clamps, made of spring steel, can be installed in the position of your

choice. The clamp fits around the PDU profile and is secured with a

fastening screw. Best is to use one clamp for every 50 cm of profile length.


C PDU: ,

How to connect the PDU to LAN? 10/100 Mbps LAN Ethernet port

Connecting the PDU to a Local Area Network (LAN) provides

communication through an Ethernet network, if the PDU is connected

exclusively, or simultaneously with the data bus.

The RJ45 connector for the network cable must be plugged into the

Ethernet port:

Connect the RJ45 Ethernet cable to the Ethernet port on the PDU

and to the Ethernet connector on the LAN device; when

connected, the orange LED – marked “lnk” - will blink

How to connect a data bus? There are three black communication ports. One is marked as sensorport,

the other two as databus ports (in and out).

The le databus port is the “incoming” databus port. The right databus

port is “outgoing”. This is especially important for devices in “bridge”

mode; a MUST HAVE for devices in bridge mode. For devices in hybrid

mode it is a NICE TO HAVE.

The serial data bus in the Schleifenbauer PDU uses CAT5 or (preferable)

patch cables.

The terms IN and OUT are arguable. Data will be send and received

by both ports but to close the data bus ring, it is necessary to follow the

connection diagram. See it as the best way to daisy chain PDUs.

How to connect sensors to a PDU? The PDU has a RJ12 connector sensor port for connecting a digital

temperature sensor, a combined sensor for temperature/humidity or a dry

switch contact

Plug and play

The PDU registers which sensor is connected and automatically adapts the

menu in the display to the sensor(s) that it has detected.

Use Schleifenbauer sensors only.

How to connect a NO/NC contact? The sensor port makes use of the RJ12 6P6C standard (= 6 position, 6 conductor). To connect a NO/NC contact on the PDU

sensor port, you have to make use of pin 1 and pin 6 ; as shown in the figure below.

Note that on a PDU only 1 NO/NC contact can be connected.

Status of the contact will be displayed. It is not possible to send a command.

Classic PDUs (= without ethernet port) do not support a NO/NC contact

P II - U

How to maintain a PDU? Internal maintenance is not an option

A Schleifenbauer Intelligent PDU may not be opened by unauthorized persons . In the event of malfunction or faults in

the PDU, please refer to the warranty conditions. Schleifenbauer Products BV will not accept warranty claims if the PDU has

been opened or alterations have been made.

⇒ Please pay attention to the operation conditions before installation and operation of the Schleifenbauer PDU. ⇒ The Schleifenbauer PDU has to be protected according to the valid installation guidelines.

The rated value of the in-series protective device may not exceed the maximum value indicated on the product. ⇒ The Schleifenbauer PDU may not be used in: a humid environment, a seriously contaminated environment or

outdoors. ⇒ The manufacturer’s warranty on the Schleifenbauer PDU becomes invalid when the QC sticker on the side of the

profile is broken. ⇒ Before turning on the PDU for the first time, make sure that it has been allowed to acclimatize to the ambient

temperature for at least 24 hours. Major temperature fluctuations can lead to the formation of condensation in the PDU if this guideline is not followed.

⇒ Please keep in mind that maximum allowed temperature for a metal enclosure is 70 °C for installation in a normal location and 90 °C for installation in a restricted access location.

How to be sure the status of switchable outlets will not change during firmware upgrade or restarting of the controller? There are no extra safety precautions necessary. Power distribution and the control over measuring and switching is

separated. This means that while updating or restarting the (controller of the) PDUs, power distribution is not interrupted.

See the section “ Power distribution meets intelligence ”

L-S P

The Schleifenbauer PDU has been designed and built for use in data centers. The Intelligent PDU may not be applied in

surroundings where a malfunction in the PDU can have consequences for life support systems. Life support systems

include any devices designated as “critical” by the U.S. FDA. Such systems are found not only in medical environments such

as hospitals, but also on offshore platforms, in petrochemical plants, in air traffic control centers, etc.


P IIA - L :

The intelligent PDU features a display with scroll buttons, LEDs and some ports for connecting accessories. Please keep in

mind that PDUs may differ in configuration and may not have a display.

(1) PDUs without an Ethernet port are called Classic PDUs. Firmware for Classic PDUs are in the FW1xxx - range (2) This option is called “Local alert reset” and must be activated via the interfaces

How to change settings locally via PDU display?

Changing settings locally via the PDU itself is not possible! You have to use one of the interfaces.

See the Administrator part of this manual how to changes the settings


https://www.lucidchart.com/documents/edit/0782ea19-03ec-4dc3-a00b-7de95d9067bf/0?callback=close&name=docs&callback_type=back&v=520&s=656

How to stop a blinking display? … local alert reset

Why do alerts occur?

Alerts are signal flags aer an event occurred. For example, if you measure temperature and the environmental conditions

exceeded a configured level - threshold - the PDU will generate an alert. This resolves in:

- SNMP trap

- the screen of the PDU will start blinking.

Aer the temperature has dropped, the event is cleared but the alert still exists. The display will blink until you “reset”

(=clear) the alert.

The LCD display only flashes when an alert is active.

Actions: press any button to stop blinking for a short period: blinking will stop so you can read the display

resetting the alert can be done by pressing both scroll buttons simultaneously; when cleared the

display will stop blinking (Note: this possibility must be activated on your device; see Admin part of

this manual)

Remember: you can reset the alert but by doing so, you do not resolve the cause of the alert!

How to check the load balance, the temperature / humidity or the status of the NO/NC contact?

In the picture you see 3 phases (L1, 2 and 3). The actual information is given in

Amperes but also graphically displayed. The higher the load, the more the bar is

filled.

The graphical bar is related to the maximum PDU rating (in the picture it is 32A).

There is nearly no load, only on L3 there is a small 0,1A.

DS = status of NO/NC contact [ 0 = open; 1 = closed ]

Te = temperature [degrees C]

RH = relative humidity [%]

How to get back to the first display?

No alerts (= no blinking display) => shortly press both the scroll buttons. You will see

the first screen in the display.

If there are alerts, first clear these (see: “ How to stop blinking display? … local alert

reset ” ) then shortly press both the scroll buttons to jump to the first page


How to check an outlet status locally?

Note: every row on the display shows the

state of 9 outlets. So the first ends with

outlet 9, the second row starts with outlet

10

In the “outlets” display you can see how many outlets the PDU has and what their

individual state is.

An overview of the possible states:

0 = off

1 = on

s = scheduled to go off

S = scheduled to go on

p = power cycling

How to check input and/or outlet measurements?

Example: input page

Note: “Input x” shows the name of the

Input. This information can be configured

from the Web Interface, Inputs tab or from

the other interfaces.

Example: outlet page

With the scroll buttons you can scroll through the pages. The total amount of

pages varies and depends on the configuration of the PDU. For example: the more

outlets the higher the total amount of pages.

In the upper example you see that page 4 of 29 is displayed.

In the lower le corner of the displayed page, you see the subject of the shown

information. In this example: input measurements of L2.

So, when you search for outlets, you need to scroll through the pages until you

reach the “outlet” sections. See lower example

Displayed information can be:

I = current [A]

P = power [W]

U = voltage [V]

Pf = power factor [%] (= real power ÷ apparent power) Et = energy total [kW]

Es = subtotal energy [kW]

How to read measurements of optional sensors and what options are possible?

Option 1: load page

Sensors are displayed on the "Load" screen whenever there are less than 3 sensors in use. When adding more sensors, one

or more pages are added to the LCD screen to show the sensors readout as shown in the images below:

DS = status of NO/NC contact [ 0 = open; 1 = closed ]

Te = temperature [degrees C]

RH = relative humidity [%]



Option 2: sensor pages

The sensor measurements are displayed in the following format:

< channel number > < sensor type > = < value >

The sensor type is indicated by a letter. The letters are abbreviations for the sensor type as follows:

Example: sensor page 1 of 2

Example: sensor page 2 of 2

Analog :

T = temperature [°C]

H = humidity [%]

R = residual current [mA]

A = AC residual current [mA]

D = DC residual current [mA]

B = Branch residual current [mA]

Digital :

I = dry switch contact

S = error status

Y = activity

For all optional sensors see www.schleifenbauer.eu

How to read Branch Residual Current measurements?

L1 + L2 + L3 + N > 0 mA …. THERE MIGHT BE FAULT IN YOUR SYSTEM !

When the PDU is equipped with a Residual Current Sensor (RCS), measurements of

the residual current are shown in the sensors pages.

( See “Example: sensor pages x of 2” in the previous chapter “Option 2: sensor pages” ).

In most parts of Europe, electrical installations must incorporate devices designed to protect people and prevent fires. Most

common among these is the residual current device, or RCD for short, which disconnects the circuit if the total for the

incoming and outgoing currents in the monitored phases and their neutral conductor does not equal 0.

There is significant potential for this scenario to occur at data centres. One example is when a switching power supply

within a computer or network equipment gives up the ghost. This in turn causes the RCD to trip and shut down operations

either entirely or for large sections. In view of this, the usual approach at data centres is to avoid RCDs and use continuous

monitoring instead. Typically, a suitable residual current monitoring device, of Type A, is used in the main distribution or

the sub-distribution system.

Standards define various types of residual current devices. The devices concerned are characterised by the types of

currents detected and their tripping behaviour under classes AC, A, F, and B.

By way of example, Type A RCDs only detect alternating currents and pulsating direct currents.

Devices sensitive to all currents, namely Type B ones, are prescribed for environments where inverters or frequency

converters are used (such as in the UPS systems found in data centres). The superimposed DC residual currents which may

occur during fault scenarios would pre-magnetize or saturate the traducers used in Type A monitoring devices, thereby

rendering measurement inaccurate or even impossible.

The residual current monitoring devices which meet the measurement criteria for Type B are based on the principle of

using special transducers for measurement purposes and recording even DC currents with real precision




Residual Current Monitoring vs Residual Current Devices?

Many devices inside a datacenter operate a switching power supply. These power supplies usually leak a bit of energy to

the protective earth, so even without failing hardware some residual current will occur.

In order to discriminate a single dangerous fault from a sum of harmless smaller faults, one needs to set up a network of

RC-sensors and monitor permanently. RC-monitoring can take place in many forms. The Schleifenbauer RC-sensor offers

Class B metering, thus enabling our customers to set-up an RC-monitoring system that prevents dangerous situations

inside the datacenter.

Where to measure residual current?

When monitoring residual current at a single location it is not possible to determine whether the measured value is a sum

of many small currents or a single larger (dangerous) one. For that reason it contributes to the safety of the personnel

inside a datacentre when residual currents are metered at many points. It makes sense to have one or more RC-sensors

inside each PDU. The search of an RC-fault can thus be limited to a single PDU or segment of that PDU.


You will find all customer specific information about the PDU in the “Custom”

display.

Adr = address of this unit on the data bus

Tag = vanity tag

Nme = device name

Loc = location of the device

How to check the way the PDU is connected to the LAN?

Information screen about how the PDU is connected to the network:

Lnk = current Ethernet link status of the device

St = IP status:

DHCP: Acquiring/Bound, Static, Static fallback ‘-‘ when there is no link

IP = IP address of the device

NM = subnet mask of the device

GW = IP address of the Gateway or Router

MAC = MAC address of the device


How can I check in which mode and with what protocol the PDU is running?

In the “IP Interfaces” display you can find information about the device mode in

which the PDU is working:

Mode = hybrid, data bus , bridge, colocation, …

See the chapter “ Schleifenbauer data bus: what is it ?” in this manual

for explanations of the term hybrid, bridge, ….

In the display you can read the status, which protocol and port number is shown

for:

HTTP

API

Modbus

SNMP

IPMode (IPv4, IPv6 or both)

When there is active communication with the PDU, the interface

which is running will turn white. In this example “HTTP”.

How to check the installed firmware version?

In the “About” display you can find the installed firmware version of the device. In

this example it is FW02.33.

It is important that the most recent firmware version is running on

the devices. This to ensure good working of the device and data bus.

Firmware and service tools can be found on “downloads” page of the

Connected devices

(ONLY FOR BRIDGE MODE)

In the le pane (part of the screen) a list of connected devices in the data bus is shown.

Also the data bus management functions can be found in this section such as:

Scan data bus

Initialise zero addresses to sequence

Reset all alerts

Device information Aer selecting a connected device, you see measurements/information and get access

to the remote operating functions, in the right pane.

Connected device -> <- Device information

There are three window sizes: S for smartphones, M for tablets and L for monitor screens.

Size of the shown screen is automatically set to the device you are working on.

Using the web interface means using capacity of the data bus and slowing down the performance of other

interfaces. Therefore it is NOT advisable to open too many web interfaces in order to prevent “hammering”

the data bus.

Classic PDUs don’t have a device type register. That is why some things do not work using SNMP: - input subtotal reset per phase, not working -> try multiple times, reset is often delayed. - outlet reboot, not working - Power (W) and Power (VA), invalid value (0.0)


How to enlarge a pane in L sized screens?

There are two possibilities:

Using the pane separator: the thin line between < and > sign:

How to select English or German language?

The login screen makes it also possible to select English or German as language

Note: in this manual, only the English screens will be shown.

How to change and save settings in the web interface?

The web interface is protected against accidentally changing settings. Related to your

profile, you might have permission to change information: see the “Permission model”.

To open protected cells, you first have to click the “Locked” sign and the status will

change to “Editable”.

When ready, click “Editable” or click the “Save changes” icon if shown, and the sign will

turn into “Locked”.

System status

This section gives you a quick view of the actual status of the PDU: are there any alerts? And if yes, what kind of alerts?

The number following aer “drops” and “overcurrent” show the OUTLET NUMBER of the last alert. In this example the is an “outlet current drop” at outlet number 6 When enabled “Auto reset alert”, alerts will be automatically cleared aer the chosen time without active alert conditions.

Device status code The code shows the status of the device in terms of errors:

0 OK Device status is OK.

1 Alert flagged One or more alerts have been flagged. Please check the other alert fields to see the cause

of the alert. It can be one of the following sources:

temperature alert

output current drop alert

input current drop alert

sensor change alert

2 Setting(s) initialized Some settings have been reset to default values. This may occur aer a factory reset or a

firmware upgrade.

4 Power-on reset The device booted aer a power loss. It can be one of the following reasons:

because of inserting the PDU power plug (mostly intentional. It can be

unintentional if someone removed the power plug accidentally)

because of a power outage (unintentional),

because of a defect in the internal power supply.

8 External reset The device has been reset by pressing the reset button on the unit.

16 Watchdog timer The device rebooted due to an internal error.

be erased. Be assured: power distribution will NOT BE INTERRUPTED during this restart !

reset alerts Clears all the alerts on the device.

Of course resetting alerts does not mean that the reason of the alert is taken away. So, an alert

can occur directly aer resetting.

Reset peaks and

dips

Clears all the registered peaks and dips on the device.

Local alert reset

allowed

Provides possibility to clear alerts while standing next to the PDU by pressing both

“Page up” and “Page down” buttons at the same time


Auto reset alert (s) In this drop-down menu, you can select how much time it will take to

automatically clear alerts aer the alert condition disappeared.

Be sure that alerts are registered by your management soware.

Settings

For devices built from February 2018 and equipped with 6-channel outlet prints have a new feature

display backlight

timeout

Setting for switching off display backlight aer certain set time:

display orientation Setting for the orientation of the LCD display. It can be set as:

peak duration

[msec]

Configurable time in milliseconds that a current overload can occur before an alert is given.

Note: do not make this time too short because otherwise alerts keep on raising!

current drop

detection

In this drop-down menu, you can select what kind of current drops

must be detected.

Please note that current drop detection is working in the following

way: When the actual current of a channel (can be input or metered

outlet) is greater than 0.5A (500mA) and drops with more than 50% of its value, then an input/

outlet current drop alert is raised.

For example:

Actual current = 0.4A, drops to 0A -> no alert

Actual current = 1A, drops to 0.6A -> no alert

Actual current = 1A, drops to 0.4A -> alert is raised


system-wide outlet

delay [msec]

Setting for delay time between 2 switch actions in milliseconds. Default value is 100 milliseconds

and values below 100 milliseconds are not accepted.

power up/down

outlet behaviour

Auto shut down is standard/default on Schleifenbauer PDUs. This means that when power

distribution to the PDU fails, all outlets will shutdown; which of course leads to shut down of

connected servers and other equipment .

The reason for the auto shut down is is to prevent peak currents damaging equipment when

power loss is solved and power distribution restarts. As a customer you are able to set the power

up mode of the outlets.

Outlet behaviour can be set as:

no switching on power up

- at power up, all outlets are kept in the off state

use system-wide outlet delay

- at power up, all the outlets are set to their last known state by respecting the fixed system-wide outlet delay

use individual outlet delay

- at power up, all the outlets are set to their last known state, but delayed by the individual outlet delay

For PDU’s built from February 2018 and equipped with 6-channel outlet prints, there is an

extra option:

no switching on power down

- in this state outlets are not turned of on power loss. If you can not select this option, you are using a 9-channel outlet pcb.

outlet unlock

override

Setting for overriding the outlet unlock registers. When this setting is enabled outlets can be

switched or power cycled without unlocking them first.

Note that this makes it easier for the user to switch outlets using SNMP, Modbus and API, but also makes it easier to switch the wrong outlet. Please keep in mind that this setting isn’t valid for the web interface. To be able to make a change through web interface, the relevant part has to be unlocked first.

maximum

temperature [ o C]

Shows the value of the upper limit that the maximum temperature is allowed to reach in degrees

Celsius. An alert will be raised if the temperature of any connected temperature sensor exceeds

the set value.

It can be disabled by setting it to ‘0’.

sensor change

Informs about the change in sensors such as new sensor, disconnected sensor or broken sensor

for this device.

extended name

support

A feature allowing the use of longer names for inputs, outlets and sensors when viewing the web

interface or using SNMP when it is enabled. This setting also affects the names shown on the LCD

display.

limited to 18 characters

setting is valid for SNMP, the web interface and the LCD display

for API and Modbus, both the original and extended name registers can be used

simultaneous and independent of each other.

when the device is configured in bridge mode, all connected devices should support the

extended name feature to work properly.

When using both Classic and ethernet PDUs in a databus, the extended name suport may lead to conflicting situations.

How to change SNMPv3 settings?

SNMPv3 user settings can be configured in the web interface: tab

“Interfaces”, block “User management”.

To change the settings of a specific user click the ‘edit’ button. Then check

the ‘change snmpv3 settings’ checkbox to edit the snmpv3 settings. When

finished, click the ‘save user’ button.

Classic PDU, so without ethernet connector and running on firmware 1.xx , don’t have a device type register. That is why some things do not work using SNMP Not working using SNMP on a Classic PDU - input subtotal reset per phase - outlet reboot - Power (W) and Power (VA), invalid value (0.0)


How to use the ‘connected devices’ section in the web interface? When the PDU is configured in Bridge mode the web interface will show a list of all devices connected to the bridge-PDU on

the le pane (or below the blue header when using narrower displays).

Initially this list is empty but will be filled while the web interface is loading data from the bridge-PDU. A selected device is

marked - yellow line - in the device list (le pane). You can switch to another device just by clicking the row in the device

list. Information and settings about the currently selected device can be seen on the right pane.

How about login profiles, usernames and passwords? The PDU user authentication model provides 5 different accounts which can be used to access the web interface and

SNMPv3.

In the web interface the user accounts are in decreasing order of access rights: super, admin, power, user and viewer.It

should be noted that super is only intended for use by Schleifenbauer personnel. The access rights of the different user

accounts, together with data bus and unauthenticated ethernet, are shown in the following table.

The default password for each profile initially equals the username of the profile. For example the default password for the

‘admin’ user profile is “admin”.

Each user can change all lesser user passwords, in addition to their own password.

Please fill the ‘User Name’ and ‘Password’ fields accordingly and then click login or press enter.


How to change factory passwords?

All user profile passwords MUST be changed at the first connection by the administrator !

In tab “Interfaces”, block “User management” passwords can be changed.

There are five login profiles:

1. Viewer = viewing only

2. User = Viewer + resetting alerts and switching outlets

3. Power = User + resetting subtotals

4. Admin = all administrator rights

And the ”factory profile”: 5. Super.

Please keep in mind that ‘super’ user profile should never be used since it allows

changing the configuration of PDU.

How to change the Ethernet link settings? By default the “ethernet link speed and duplex mode”-setting is set to autonegotiation . With this setting the link speed

and duplex mode are automatically configured with the link partner (e.g. Network Switch).

You can also configure the link speed and duplex mode to a fixed setting. You can choose from the following options:

Autonegotiation

10 Mbps Full Duplex

10 Mbps Half Duplex

100 Mbps Full Duplex

100 Mbps Half Duplex

When changing this setting you must also configure the link partner correctly! Otherwise you will not be able

to connect to the PDU remotely.

If this setting is changed in the wrong way and you are not able to connect, change the setting of the link

partner to be able to access the PDU again. If this doesn’t work you can try a factory reset .


N

DHCP and default address

In general, the Dynamic Host Configuration Protocol (DHCP) protocol can dynamically configure the:

IP address

subnet mask

gateway address

Domain Name System (DNS) servers

By default, the PDU is configured to get the IP address from DHCP automatically. If the PDU does not receive an IP address

within a set time, it will proceed using the default address:

192.168.1.220

(subnet mask: 255.255.255.0)

How to configure the IP settings manually? The IP settings can be manually configured by using the web interface:

Actions: go to the <web interface> , tab < Interface >, block < Network Configuration >

disable DHCP

Fill in the “Static IP Settings”

Restart the CPU: go to tab < System >, block “Reset”

When using ‘DHCP fallback to static IP’, it is recommended to enter a unique IP address for each PDU. This

approach prevents all of the PDUs from being assigned the same IP address in the event of a faulty DHCP

server.


How to setup IPv6? Since firmware version FW2.44, IPv6 support has been introduced in the Schleifenbauer PDU. This feature is disabled by

default.

An IPv6 address consists of 8 blocks of 4 hexadecimal digits separated by columns ( : ). Consecutive blocks of zeroes can 1 2

be substituted with a double column ( :: ) and leading zeroes can be omitted. By default the static IP is "::" which translates

to 0000:0000:0000:0000:0000:0000:0000:0000.

IPv6 Autoconfigure (SLAAC)

By default the PDU will try to obtain its IPv6 address through a process called "stateless local address auto configuration"

(SLAAC). This setting can be turned off in the web interface by setting "IPV6 Autoconfigure" to "disabled".

The PDU will try to find a router by sending router solicitation packets via ICMP6 using its link-local address. This means

that a IPv6-enabled router must be available on the network and it must send ICMP6 router advertisement packets in order

for the PDU to obtain a valid IP6 address.

When "IPV6 fallback to static IP" is set to enabled in the web interface, the PDU will use it's configured static addresses as

fallback when a router cannot be found.

Static IP

To use static IPv6 addresses the PDU must either have it's "IPV6 Autoconfigure" setting disabled or "IPV6 fallback to static

IP" enabled in the web interface.

These settings can be found under " interfaces → network configuration".

To change the static IPv6 addresses, fill in a valid IPv6 into fields "IP6 address 1" and/or "IP6 address 2" as shown in Image

1.

How to configure IPv6? The IPv6 settings can be found in the PDUs web interface under " interfaces → network configuration". The PDU will

always generate a Link-local address which starts with "FE80::". This address is auto-generated and loses its scope at the

first encountered network node. 3

The IP6 addresses can be found on the web interface or on the "IPv6 Link" page on the PDU's built-in LCD screen as shown

in Image 2.

To enable it the user must login to the PDU using the ipv4 address presented on the display. Aer logging in onto the web

page of the PDU, select the tab " interfaces". Under network configuration there's a drop-down box called "IP Protocol 4

select" as seen in Image 1. By default this will be set to "IPv4 only". To enable IPv6 set this to either "IPv6 only" or

"IPv4/IPv6 dual-stack".

Note that selecting "IPv4 only" or "IPv6 only" requires one of the filtering ranges to be all zero (allow all addresses). This is

to prevent users from locking themselves out. Naturally filtering can be configured aerwards when the user has

connected to the bridged and/or hybrid PDU using the protocol previously specified.

Enabling IPv6 will also add an additional page on the PDUs display: see image 2. The current IP Mode is also displayed on

the display; screen "IP INTERFACES".

I mage 2: ipv6 page on PDU display

How to set up IPv6 address filtering? As with IPv4, IPv6 address filtering settings can be found under

" interfaces → network Access control" from within the web interface.

The web interface shown in image 3 will allow you to specify 3 IP ranges which grant access, anything outside of these IP

ranges will be blocked. If you wish to configure only a single range, you should fill in this range 3 times.

All "allowed IP6 range" fields must be filled, in order for the filter(s) to have effect. Setting any address with prefix "0" will allow any address to access the PDU web interface, SNMP, modbus etc. Setting the

address to "::" (all zero's) and the prefix to a number between 0 and 128, will limit the allowed IP scope to the network the

PDU is connected to. Filtering will then


Example:

Setting a filter of A76F::D222:12FF:FEB0:F48/64 will allow any address starting with A76F:0000:0000:0000: (A76F::) but other

addresses such as A76A::32D4:731B:F17B:6 will be blocked. for more detailed explanation see the wikipedia page on IPv6

subnetting. 5

Image 3: IPv6 filtering ranges

Image 4: PDUs current IPv6 addresses.

How to send SNMP Traps with IPv6? The PDU allows you to set 2 SNMP trap destinations. traps are fired when an alert has been generated within the PDU.

These destinations can be found under " interfaces → SNMP" in the PDU web interface. The "trap destination address"

fields can be set to any destination including an IPv4 address (when IPv4 is enabled) and an IPv6 address as seen in Image

5.

Image 5: IPv6 traps

The development of the PDU firmware is an ongoing process. With every new release not only issues are fixed, but new

features appear and the data bus will be more stable and speed will be increased. Not installing the newest firmware

means that you do not make use of the latest technology.

Because of the data bus ring, upgrading of all attached devices can be done remotely! During the upgrade process the

power distribution will not be interrupted. Our firmware, firmware tools and manual are cost free: both download and in

use.

When a Schleifenbauer Gateway is in the data bus you need to upgrade the Gateway firmware first. This firmware can be

found on the documentation page of the Schleifenbauer website.

The latest firmware, manual and updater tool can be found on the downloads page of our website www.schleifenbauer.eu .

How to stop the alert signaling? ...auto reset alert From firmware 2.40 on it will be possible to select a duration time aer which the alert will be cleared aer the cause of the

alert is not present anymore. It will be no longer necessary to clear the alert on the PDU or via an interface aer the event

which led to an alert is gone

But remember: an alert does not occur without a reason. So it is important that the alerts are recorded/logged in an

management system.

How to upgrade the firmware? ...using SPST

SPST stands for "Schleifenbauer Products Service Tool”. This is a program which aims to aid customers in analyzing and

maintaining their network of Schleifenbauer PDUs and DPM-energy meters. It does so by offering the following features:

You are able to “quick scan” the status of your databusses

You can upgrade/ downgrade firmware in a very easy and simple way

You can remotely mass configure your databus devices

You will decrease problem solving lead time

You can download SPST from www.schleifenbauer.eu where you also can find the SPST-manual. Please read the manual

before you start using SPST and you will find out that this tool will make firmware updating and mass configuration a lot

easier.



S : ?

The intelligence of Schleifenbauer PDUs (and DPM

energy meters) makes it possible to read and manage

devices remotely over IP. You can for example enter the

data bus via the web interface, MODBUS and SNMP.

There are all kinds of possibilities using the data bus:

whatever configuration you want to build, with the data

bus it is possible.

Data bus and power distribution are two separate

functions of the Schleifenbauer PDU. This means that all

actions done via the data bus do NOT interfere the

distribution of power to the IT equipment in the racks.

Advantages of the data bus:

easy to build: just pick a PDU and connect it to

your LAN, daisy chain the rest of the PDUs and

you have made a data bus

remote updating of the firmware

Explanation of the figure:

the PDU/DPM-energy meter that is connected

to the LAN must be in “ BRIDGE ” mode; this is

the MASTER device

all “daisy chained” devices must be in “ HYBRID ”

mode; these are the followers: the BRIDGED

devices

How to prevent data losses because of cable cuts? ...ring redundancy Normally the advantage of an IP solution per PDU is that a cable cut will not affect the other PDUs on the bus. This could happen in a normal daisy chained serial bus topology.

However, Schleifenbauer has made their bus redundant so that a single cable cut will not affect the readout or control of the PDUs; it will try and get access via the alternative route on the ring. A cable cut is detected by our firmware and an error message will be submitted to the database. The disadvantage of a serial bus topology is therefore covered in the Schleifenbauer system.

See Part I “How to connect a data bus” on the PDU


How to make a data bus using Schleifenbauer Gateway?

In the figure above you see a small data bus-ring with

four PDUs connected to the Schleifenbauer Gateway.

The Classic PDU has NO ethernet port, so a

(Schleifenbauer) Gateway is needed in order to get PDUs

connected to your LAN.

The sequence of devices does not affect the performance

of the Gateway or the data bus. Though the more devices

you place in the data bus, the slower data transmission

will be.

It is advised to close your data bus-ring. To do so, you

connect the last device in the data bus also to the

Gateway (blue lines in the figure). In a closed data bus

ring the Gateway can reach all connected devices via IN

and OUT data bus-ports (clockwise and anti-clockwise).

Advantage : with one IP-address you can collect data

from a number of connected Schleifenbauer-devices (not

only PDUs but also the Schleifenbauer DPM-range

(=energy meters)

Disadvantage : Gateway uses 1U

Problem solving: when the Gateway fails, you can

change to the next configuration: using the “bridge”

mode

Data bus communication is 0,2 seconds per

query (e.g. input measures block). Therefore

we advice to make rings with a maximum of 50

devices which means that querying each

device once will last appr. 10 seconds

How to connect the data bus to LAN without a Gateway? ...using a PDU!

In the figure you see a small data bus-ring with only four

devices connected to a LAN: a Classic PDU and PDU with

ethernet port. The device connected to the LAN must

have an ethernet port and be in "BRIDGE" mode. All

other devices should be in "Hybrid" mode. The BRIDGED

device takes over the function of the Schleifenbauer

Gateway.

You can connect numerous of Schleifenbauer devices to

the device which is in BRIDGE mode: PDUs and DPM3's (=

3 channel energy meter) as well as Classic PDUs and

DPM27 (= 27 channel energy meter). The sequence of

devices does not affect the performance of the data

bus-ring. But, the more devices you place in the data

bus-ring, the slower data transmission will be. The

scheme shows that you can use different kind of

Schleifenbauer devices in a ring which makes the system

easily scalable to your needs. It is advised to close your

data bus ring. So it is best to connect the last device in

the data bus to the device which is in BRIDGE-mode. In a

closed data bus ring you can reach all connected devices

via IN and OUT data bus ports (clockwise and

anti-clockwise).

Advantages : (1) when only using devices with ethernet

port: only the device in BRIDGE mode uses one

IP-address. (2) you can select any device connected to

your LAN as long as you place it in BRIDGE mode, (3)

investment in a Schleifenbauer Gateway is not

necessary, (4) the system is easily scalable

Disadvantage : MySQL can not be used

Data bus communication is 0,2 seconds per

query (e.g. input measures block). Therefore

we advice to make rings with a maximum of 50

devices which means that querying each

device once will last appr. 10 seconds

PART IV - P S

How to perform a “Soware reset”? And why? When Interface-settings are changed the CPU has to be started. In the webinterface a pop up will appear when needed:

Remotely

Soware reset can be done via the web interface. It is important to understand that a soware reset has no impact on

power distribution of the PDU. So a reset can be performed at any time without having to interrupt the power supply and

without losing the settings in the PDU.

Locally

The soware can be reset using a paperclip or some other kind of thin and rigid rod to press the reset button. This button is

mounted behind the hole labelled as ‘rst’ on the PDU which is next to the Ethernet connection port.

How to perform a “Factory reset”? If the PDU can no longer be accessed via the LAN, for example, because settings have been changed, restoring IP access

may be needed. The following procedure causes the PDU to adopt various default values, which allows it to be detected on

the network again without losing any of the other settings in the PDU. However, the power supply must be interrupted in

order to perform this restore procedure! The procedure is described in five steps:

1. Interrupt the power supply to the PDU.

2. Restore the power supply.

3. Wait for one second and aerwards press the reset button using a paper clip.

4. Wait for a further second and press the reset button again.

5. Wait for a further second and press the reset button again.

The PDU has now adopted the default values for the IP settings. The access control fields and the web server settings have

also been returned to the standard values.

Please note that because the power is removed, outlets will also be out of power. Hence, during this process there won’t be

any measuring.

Please keep in mind that kWh totals will NOT be reset during this process.


How to reset peak current?.....and other dips or peaks Example: you have set the “overcurrent alert at” on 5.00A in the < input > tab. At a certain moment you see an alert in the

webinterface dashboard. You check the Inputs-tab and see a peak current of 8.30A:

You can clear the alert as you already know locally or by the reset button in the <Reset> block in the System-tab but the

peak current will not be cleared. You have to do this by clicking the <reset peaks and dips> button in the <Reset> block of

the System-tab:
